5 Claims.

This invention relates to shoes, and it is an lobject of the invention to' so form the sole of the shoe to combine the inner and outer soles in one lamination of material, together with means f5 for properly and conveniently maintaining an arch support in desired position.

The invention consists in the details of'construction and in the combination and arrange- Y. -ment of the vseveral partso! my improved shoe l whereby certain important advantages are at- Y `tained andthe device rendered simpler, less expensiveand otherwise more convenient and advantageous for use, as will` be hereinafter more fully set forth.

. The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying draw- 20 ingr whereinz- Figure 1 is a view in side elevation of a shoe constructed in accordance with an embodiment of my invention:

Figure 2 is a view in top plan of the sole as comprised in the structure of the shoe;

Figure 3 is a sectional view taken substantially on vthe line 3-3 of Figure 1;

Figure 41s a sectional view taken substantially on the line l-I' of Figure 1.

In the accompanying drawing I illustrate an embodiment of my invention wherein the shoe is of a sandal type although I do not wish to be understood as limiting my invention to this particular type of shoe but that my inventionvcan be employed to equal advantage in the production of shoes for men, women and children.

In the construction of my improved shoe the piece of leather or rubber compound or other desired material from which the sole S of the shoe is cut is of a thickness equal to` the com'- bined thickness of the ordinary inner and outer soles. After the cutting of the sole S by a con-.- ventional rounding machine the sole is placed in a channeling machine. The channeling machine splits the marginal portion of the sole S, as at i, entirely therearound and to a distance inwardly 'of the sole desired. By this operation the sole has its central or intermediate portion solid with the marginal portion thereof divided to provide for the outer sole and the inner sole.

When the shoe is of a sandal type as illustrated in the drawing, an edge binding 2 is sewed to the marginal insole portion while of course the edge of the outer sole portion is trimmed and set in 55 y the usual way.

(Cl. 36-12) Y Straddling from the rear the central connected or solid portion of the sole S is an arch support or shank 4. 'I'his support or shank I is substantially U-shape in form and is'preferably of steel. The shank is of such size and so constructed to extend around the back of the heel of the sole and stopping at substantially the ball portion thereof.

` The straps 5 of the sandal upper are extended within the marginal slit I and are adhesively or otherwise flxedly anchored to the upper or inner soleI portion. The upper and lower portions of the slit are then adhesively connected and in so connecting the same the marginal portion of the sole immediately after applying the'cement is preferably pounded hard with a hammer for about ten minutes or, if preferred, the entire shoe may be put into a conventional conveyor press. Afterthe upper has been applied to the sole the heel H is placed in position in the conventional manner.

It is also to be particularly noted that the shank or support l fits tightly against the inter- -mediate solid portion 3 of the sole S thereby giving the sole a double-shank support.

From the foregoing description itis thought to be obvious that a shoe constructed in accordance with my invention is particularly `well adapted for use by reason of the convenience and facility with which it may be assembled and used, and it will also be, obvious that my invention is susceptible of some change and modification Without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

1. A shoe comprising a combined inner and outer sole formed from a single piece of material cut to desired design, the edge of the sole being slit to divide the.v marginal portion into an outer sole part and an inner-sole part, the central portion of the sole being solid, a substantially U-shaped shank bridging the central solid portion of the sole, and a shoe upper extending within the slit and secured therein.

l 2. A shoe comprising a combined inner and outer sole formed from a lsingle piece of material cut to desired design, the edge of the sole being slit to divide the marginal portion into an outer sole part and an inner sole part, the central portion of the sole being solid, a substantially U- shaped shank bridging the central solid portion of the sole, said shank extending from the heel end of said solid portion to the ball portion of the sole, and a shoe upper extending within the slit and secured therein.

3. A shoe comprising a combined inner* and outer sole formed from a single piece of material cut to desired design, the edge of the sole beingl slit to divide the marginal portion into an outer sole part and an inner sole part, the central portion of the sole being solid, a substantially U- shaped shank bridging the central solid portion of the soie, said shank extending from the heel end of said solid portion to the ball portioniof the sole, said shank snugly engaging the cen- *ral solid portion of the sole, and a. shoe upper vided by the slit.

edge slit with its central portion solid, 'a substantially U-shaped shank mounted within the slitted portion and bridging the solid portion from the rear of the sole, and a shoe upper having its marginal portion extending within the slit and secured therein.

5. A shoe comprising a sole having its margina] edge slit with its centra1 portion solidya substantially U-shaped shank mounted within the slitted portion and bridging the solid portion from the rear of the sole, a shoe upper having its marginal portion extending within the siii; and secured therein, and adhesive means for eenw necting the'overlying portions of the sole as nrw
